The Controller is the Sentinel system's dash interface. No laptop, no phone — the state of the vehicle's lighting and power lives where the driver can see it.
The Controller shows what the Sentinel system is doing. Connect an In-Site reader and it also shows what the vehicle is doing — live data and trouble codes, on the same screen the crew already uses.
How In-Site connects →It's a working screen for working vehicles: big targets, high-contrast status, and the information a driver or officer actually needs at a glance. Detailed hardware specifications publish as the Controller clears development.
